ADVERTSNG AND CALENDAR CLOCK.

Application 'filed March 13, 1925.

Qur invention relates to advertising calendar clocks and the object is to provide in a single device a novel calendar' clock and advertising medium which'may to good advantage be placed in banks, druo stores, churches, halls and other public places and may also be used as a house clock.

ln the accompanying drawings:

Fig. 1 is a front elevation of the complete device with the outer case or inclosure.

Fig. 2 is a front elevation of the mechanisin and its frame removed from the inclosure, the dial and its hands removed, and fragments broken away to expose certain parts.

g. 3 is rear elevation of Fig. 2.

i g. l'is sectional top view on the line alf-i in 2, with the paper strip carrying the dates and advertisements omitted and the mechanism frame 76 of the time piece almost entirely closed at its top so as to avoid showing of all the common clock `mechanism.

Fig. 5 is a portion of Fig. 4 with the escapement arms 62, 62 and some other parts omitted. f

6 is a section on the line 6-6 in Fig. 5, and a portion of the roller 54 and its disc 60 and intermediate frame 29.

T is a section on the line 7-7 in Fig. l with top plate 25 of the main frame added.

Referring to the drawings by reference numerals, the outer case or inclosure consists of a bottom 10, top 11, end walls 12, rear wall 18 and front wall 11i, the latter hinged at and has a suitable catch. 16 and is provided with an aperture 17 with a small door 18 hinged at 19 and held closed by a catch 20. Said small door has a round glass 21 through which is seen the clock dial 22 upon which the hour hand 23 and minute hand 24C indicate the time.

rBemovably mounted in the case is a main metal frame consisting of a bottom plate 25, top plate 25", end plates 26, 2'? and a few upright flat frame bars 28, 29, 30, 31 and 32 (see Fig. i). The clock dial 22 may be secured on the frame bar 32, as in Fig. 4.

rEhe front wall or door lli is provided with a small sight slot 33 through which is displayed a fixed advertisement 3d. Through a larger paper 36 having printed upon it the successive days and dates of a year, as indicated in Fig. l, and to one side thereof a variety slot 35 is displayed a long slip ofv Serial No. 15,401.

advertisements in the spaces marked Ad, rid in Fig. 2. Said strip of paper 36 is guided to move in vertical direction near the sight slots, by ltwo rollers 37-38 (see Figp) and has one end attached to a roller on which the strip is originally wound. rPhe strip is held frictionally by a curved leaf spring et() to prevent accidental unrolling. The other end of the strip is secured to a winding roller l1 having a shaft 42 with a bevel gear d3 fixed on it (see Fig. 4f) and driven by a. bevel gear 4d, fixed on a shaft d5 having a pinion d6 driven by a gear 47 shaft i8 and spring 49. The latter may be wound `by a suitable key put on the stein 50.- 51 is the ratchet wheel and 52 the. pawl to aid in such winding. Said driving mechanism is mounted in a frame 53 secured to the frame bar 30 and with its frame may be termed a spring motor. 55 and 56 are bearings for the sha-ft 42.

The spring motor would wind up the e-ntire strip 36 in a few minutes instead of a yea-r. It is therefore controlled by the clock shown and a controlling roller 57. This roller is provided near each end with radial pegs 58 engaging in perforations 59 in the strip, so that the strip can only move and -xhibit the next date on it when the clock releases it at midnight, one step each night, by an escapement which in the present illustration is as follows:

At one end of the roller 57 is fixed a disc or wheel 60 having four equidistant teeth 61, each of which when turned upward is engaged by an escapement lever 62, or for ietter effect, two levers 62 and 62a are used; both levers pivoted at 63 side by side in a special small frame 64 which consists of two parallel plates, secured together by the pivot 63 and a similar rivet 65. Mounted in this frame is a cam 66 (best shown in Fig. 6) having a tooth 67 wide enough to lift both levers 62 and 62a above the upper tooth 61X of disc 60; but it will not lift both levers fully at the same time because each lever has a clearance notch 68 and an angular shoulder 62 forward thereof and as said shoulders are one ahead of the other the result is that lever 62 is first raised and allowed to drop upon the tooth 61x (see Fig. 7) say fteen or twenty minutes before twelveoclock midnight and more exactly at midnight the cam will have fully raised lever 62a and thereby permitted the.' disc 60 to uns inale one fourth ot a revolution. The idea of having tivo levers is that the lever G2 should rest on the dise and be sure to stop the next tooth Gl which is eoining so quickly that a single lever might not get time to stop its upward inovenient and also he drawn dovvnivard hy gravit.;Y to engage the next tooth (S1 in tine to stop it. But loy using` a light lever and a spring' (not shown) pressing' it downward, a single lever inal'yY also answer the purpose.

The cuni G6 is hved on a shaft 70 which is journaled in the traine tiel: an( also in the traine hars 3l and 321 and is 'tinted in :l gear Wheely '7l which is twice as large as the pinion T2 drivingit and which is fixed on the hour arhor 73 holding' the hour hond 23. This will explain that when the hour hand has inode two revolutions the 7l and earn 66 have inade onli,T one revolution and vill thus allow the calendar to he changed onlyv at midnight hy the spring motor operating it.

ln Fig. 'Ttis a spacing coller liietvveen the traine. (ill and the har 32 ot the mein :traine and 75 is the shaft Carin-'ing the ininute hund 2% ot the clock.

its tor the clock itself it is preferably an eight dey clock. lts 'traine 7f3 contains the required mechanism ot' which in the present illustration onlyv the main spring` T7, gear 7TH. winding ratchet TS and eseapeuient if) and WindingY stein as 8O or 8l are shoivn.

ln lli 3 is shoivn that the 'framework muy have an aperture S2 through ivhieh to reach the stein 8() with a key ii. ithe desired to ivind the clock from the rear ine. Likeivise, a clearance S3 and Stem 84 indicate that the clock may have its hands adjusted troni the rear ot Vthe device. ln said vienv 85 is a guard ahout the moin spring'.

lit the end of each calendar year the strip 3G is removed and replaced h v a nenv one for the next year, and such neviv strip may carry the saine. advertisements as the one displaced, or itl may have new and different advertise- .inentsg all as may he desired.

Jill the apertures in the trent .vall may he clos-ted by either glass, niieev or other trans- ;arent material.

lllhat .ve claim is:

lu a device o'il the class descrihed` haw ing; a inotor driven roller and a Vtleiilile display strip arranged to he ivound upon it troni another roller; e. controlling roller rotated h v the Adexihle strip and having at one end u dise with radiating' teeth spaced to correspond to the itenis displayed each da)Y hy the strip; two horizontally disposed levers having; each one end on a pivot, so as to siting side hy side in vertical planes and resting norinailli,7 upon the upper edge ot the disc so as to obstruct its rotation Yh v contacting with its teeth; each ot' said levers having its lower edge pr vided with a shoulder dispos-Jed one nearer than the other to the pivot; u cani shat't havinga fixed Cain arranged to engage and raise said shoulders one shoidil)v after the other, a geen' tixed on the cani shaft. a clock. a pinion lifted on the luiur-hantl arhor ot the elocl: and meshingY .vith seid gear, said pinion being' halt the diairneter ot the geur, so as to cause the cani to act only once in twenty-tour hours.

ln testimonyY whereof ive attix our signatures.
